I indeed misunderstood, didn't realize that was you yourself you linked to. Sorry we are on the same boot it seems. Still, you're wrong about Nostr being useless without Lightning. And it is unhelpful to suggest it is.
You stand corrected, and I stand corrected too because I just watched https://www.youtube.com/watch?v=Tbt3jL1Ms0w (as suggested by other user in another comment) and it finally clicked.
